Introduction

Circuit breakers are an important component used in various applications. Like any other electrical equipment, circuit breakers must be designed according to specific standards in order to ensure they can withstand the current flow and also prevent potential hazards. The model 452-2-K34-FN2-75A is an example of a circuit breaker that is designed with specific features and functions for specific applications. This article will discuss the application field and working principle of the 452-2-K34-FN2-75A circuit breaker.

Application Field

The 452-2-K34-FN2-75A circuit breaker is designed for use in a variety of applications. It is primarily used in industrial and commercial settings and is designed to be used in medium voltage applications. It can handle up to 13.8 kV and has an interrupting rating of 25kA. It is also designed to handle both AC and DC currents, making it suitable for a wide variety of applications. In addition to its use in medium voltage applications, the 452-2-K34-FN2-75A circuit breaker is also used in high voltage applications. It can handle up to 17.5 kV and has a higher interrupting rating of 40kA. This makes it suitable for use in installations with higher voltage levels and tougher environmental conditions. The 452-2-K34-FN2-75A circuit breaker is also designed to be used in a variety of environments. It is designed to withstand temperature extremes from -40°F to 158°F and can be submerged in water up to depths of 25 feet. Furthermore, it is UL listed and CE certified, making it suitable for use in countries that require such certifications.

Working Principle

The working principle of the 452-2-K34-FN2-75A circuit breaker is relatively simple. When the electrical current reaches a certain level, the breaker trips and shuts off the current. This limits the potential damage to appliances and other electrical components that are connected to the circuit. The operation of the breaker works by taking advantage of the magnetic fields created by the current. When the current reaches a pre-programmed level, the magnetic field in the circuit breaker reaches a certain level, which triggers the breaker to trip and shut off the current. In addition to the magnetic field, the 452-2-K34-FN2-75A circuit breaker also uses a series of contacts to ensure a reliable operation. The contacts are designed to be in close contact with each other when the breaker is closed and are separated when the breaker is opened. This ensures that the current is properly interrupted when the breaker is tripped.

Conclusion

The 452-2-K34-FN2-75A Circuit Breaker is an example of a modern circuit breaker designed for use in a variety of applications. It is designed to operate at up to 17.5kV, has an interrupting rating of 40kA, and is designed to withstand a wide range of temperatures and environments. It operates through the use of a magnetic field, which when triggered, trips the circuit breaker and shuts off the current. The 452-2-K34-FN2-75A Circuit Breaker is a reliable and cost-effective solution for protecting electrical equipment and systems.
